With the days getting darker and the nights colder, we're now turning the heating back on. For many, our home environments have radically changed since the lockdown. A recent Morgan Stanly report showed that two-thirds of UK white-collared workers were now working from home, with only 34% of people who could return to working in their offices, choosing to do so.
As a result, our boilers are likely to be staying on for longer periods and because intrusive background noise can be a distracting productivity killer, its never mattered more to chose quiet boilers and heat pumps.
Since being founded in 2012, Quiet Mark's expert team of acousticians have tested almost 500 boilers with less than 30% qualifying for Quiet Mark accreditation. Noise ranges from just 32dB for the smallest up to 65dB for the largest boilers. But as we assess boilers in a like-for-like manner, 50dB may be considered 'quiet' for some kW output models but is far too loud for others. This is where Quiet Mark helps consumers by doing the work for them and only certifying the quietest boilers of their type.
Here is a selection of just a few of the boilers and heat pumps to have made the grade, with more to view on our Quiet Central Heating Web Page. Each one helping to make your home warm and cozy, without those annoying gurgles and rattles!

The Aerona³ R32 inverter driven air source heat pump range is Grant’s cleanest and most efficient heat pump range yet. The first monobloc R32 ASHP to be launched in the UK, Grant’s Aerona³ R32 heat pumps use the more environmentally friendly R32 refrigerant which has a significantly lower GWP value.
All of Grant’s R32 heat pumps have exceptional SCOPs, with the 13kW model HPID13R32 achieving a SCOP of 5.41 at 35°C and the 17kW model HPID17R32 achieving a SCOP of 4.54 at 35°C. MCS approved, Grant’s R32 heat pumps operate with incredibly high efficiencies while also being notably quiet.
Cleverly designed with the key components located to the front of the models allowing for easy access for installation and maintenance, Grant’s heat pumps are straightforward to work with while also being easy to control for householders.

Right pumps form Salamander's premium product range, offering the most powerful performance. Utilising centrifugal force, they are quieter and more flow efficient than regenerative pumps. The universal versions also have added technology that protects the pump from the most common issues.
These pumps will boost hot and/or cold water supplies to thermostatic or manual mixer shower valves, supplying a wide range of shower types and shower heads, individual taps, cisterns and other bathroom and whole house applications. Options are available for boosting champagne spray, massage function and multiple body sprays too.
Suitable for use in a gravity fed system, positive head and universal (negative head) models are both available.

From the outset of designing the Warmflow Zeno heat pump it was conceived to be one of the most efficient appliances in its class. Unlike most other heat pumps which produce heat at a fixed output, this heat pump makes use of the latest variable speed compressor technology to produce heat at the rate you need. This gives the heat pump a wide output range and it automatically modulates within this range depending on your heat demands. For ease of installation, the pump and flow switch are conveniently housed within the heat pump casing. This speeds up installation and minimises wiring and plumbing needed on site.
The unit also has an inbuilt monitoring system, which monitors flow temperature and system temperatures for easy commissioning. A dedicated wiring centre greatly simplifies connection to external wiring and sensors making this heat pump very easy to install and service. Independent tests have shown its efficiency to be up to 555% at A7W35. This means that for every 1kW of electricity consumed 5.55kW of heat is produced.

Vaillant’s aroTHERM plus is one of the greenest heat pumps available on the market and is designed to exceed the heating requirements of today. The aroTHERM plus uses a natural refrigerant which has an exceptionally low global warming potential of just 3.
The Quiet Mark awarded aroTHERM plus heat pump range is available in 3.5kW, 5kW, 7kW and 12kW outputs, making it suitable for most domestic properties and can be cascaded for commercial use.
Without compromising on performance, the aroTHERM plus can provide up to 25% more usable hot water and can reach flow temperatures up to 75°C, removing the need for an electric immersion heater for legionella protection.
In addition to their aroTHERM plus, Vaillant’s flexotherm, geotherm and arotherm Split heat pumps have also achieved the Quiet Mark.
